Since QNX - understandably - lost any and all interest in general-purpose computing, I kind of lost track where it was going (I used to have such fun with it - yup, 2004, before I even joined OSNews). Apparently, they just released version 6.5 SP1. It contains optimised memory performance, better networking and USB stacks, improved file system performance, and more. I'm sure these are all things we'll see trickle down to BlackBerry OS 10.

Well, it's also the fault of the company that basically takes any name they like, cleans up only after the fact (like it was also with the iPhone IIRC)

And I imagine that, for codebase of such importance (used not only in a fairly crucial line of ~switches, also automotive usage or with... Canadian nuclear reactors), buying of QNX per se wouldn't even be required - the code is certainly in escrow, with arrangements made a long time ago for ownership transfer, were something to happen with its parent company.
